LEIVIS H. HEIVITT, OF CORTLAND, NEIV YORK.

Specification of Letters Patent.

Patented Sept. 5, 1905.

Application filed. March 17, 1905. Serial No. 250,552.

To a. whont it may concern.-

Be it known that I, LewIs H. HEWITT, of Cortland. in the county ofCortland, in the State of New York, have invented new and usefulImprovements in Coal Storing and Screening Apparatus, of which thefollowing, taken in connection with the accompanying drawings, is afull,clear, and exact description.

This invention relates to an apparatus designed for use by retaildealers of coal.

The object of the invention is to provide simple,convenient, andinexpensive means for furnishing to the consumers cleaner coal than hashitherto been usually put in the market; and to that end the inventionconsists in the novel construction and combination of the componentparts of the coal storingand screening apparatus hereinafter described,and set forth in the claims.

In the accompanying drawings, Figure 1 is a front elevation of anapparatus embodying my invention, the front wall of the storehouse andportions of the elevator-shaft being removed to illustrate the interiorof the apparatus. Fig. 2 is a vertical longitudinal section on lineXXinFig. 1. Fig. 3is ahorizontal section on the line Y Y in Fig. 1, and Fig.I is a vertical transverse section of a modification of my invention.

Similar letters of reference indicate corresponding parts.

A represents a three-story storehouse or building in which the coal isstored for delivery to the consumers. The ground-story of thisstorehouse is provided with a suitable driveway B for the passage of theconveyances designed to receive coal from said storehouse. The secondstory of the storehouse is divided into compartments or bins O (J forreceiving coal of difierent grades. The bottoms of the bins are inclinedto the driveway and lead to discharge-ports a a, which are provided withdrop-doors?) Z) for closing said ports. I preferably form the drivewaythrough the center of the storehouse A and arrange the bins U C in rowsalong opposite sides of the driveway, as shown in Fig. 1 of thedrawings. Each of the discharge-ports a is provided with a chute a,leading to the driveway and hinged to swing upward from its inclineddelivering position. The bottom of the said chute I form of heavywire-netting or other suitable open-work floor to screen the coalpassing from the bin U to the vehicle designed to receive said coal. Iprefer to employ suitablyarranged chains and pulleys for lowering thesaid chutes to and raising the same from delivering positions. as shownin Figs. 1 and 2 of the drawings.

E represents a suitably-supported elevator, which is inclosed by a shaftS, disposed at a corner of the storehouse and extending from the bottomof the building to a point some distance above theroofthereof. In theupper .portion of the said shaft is supported a hopper (7, provided witha suitable opening through which the coal is discharged into the topstory of the storehouse, which opening is provided with a gate (1 tocontrol the discharge. To the floor of this upper story is secured atrack 6, upon which is mounted a suitable dumping-car l) for receivingthe coal from the hopper and conveying it to the bins C (J, disposed inthe story below. In case the coal is delivered to the elevator by meansof railroad-cars. as represented at F in Fig. 1 of the drawings, whichcars are provided with hinged drop-bottoms, as shown at F, I provide achute f, which leads from under the railroad-track to the bottom of theelevator E. The upper end of this elevator is extended some distanceabove the hopper (Z and casts the elevated coal onto a screen which isinclined to conduct said coal into the hopper (Z, from whenceit is drawnwhen desired into the car D, by means of which it is conveyed to the bindesigned to receive it. By arranging the screen in this manner the dust,&c., from the coal is caused to be deposited in the shaft S, thusprotecting the person employed in the upper story for operating the car.

Ur represents a suitable motor for operating the elevator.

It will be observed that the described apparatus screens and cleans thecoal during.

the process of storing it and again screens said coal during itsdelivery from the storehouse to the consumer. who thus receives cleanercoal than is usually put in the market. In Fig. I ofthe drawings I haveshown my coal storing and screening apparatus located on the bank ordock of a canal or other navigable waterway (indicated at L) andarranged to receive the coal direct from a boat F*. In this case thedriveway B is at the exterior of the storehouse and extended along theside thereof farthest from the waterway L. The interior of thestorehouse is divided into a single row of bins C, inclined toward thedriveway and leading to the screens a, which conduct the coal to thevehicle N for delivering the coal to the consumer.

to deposit the screenings at the exterior of having a discharge-port anda drop-door there- I for, movable screening-chutes for delivering thecoal therefrom, means for moving the chutes to and from operativepositions, a hopper for receiving the coal to be stored and disposed atthe upper story of the structure, a gate operative for controlling thedischarge from the hopper, a screening-chute for conducting the coalinto the hopper and disposed the storehouse, an elevator for conveyingthe coal from the bottom of the storehouse to the top thereof andcasting the same onto the screening-chute, a motor for operating saidelevator, a track in the upper story, a car mounted on'said track belowthe hopper and serving to convey the coal therefrom to the aforesaidstoring-bins as set forth.

2. A coal-storehouse consisting of a threestory structure and providedin the second story with storing-bins having dischargeports and doorstherefor, a driveway at the lower story, hinged delivery-chutes leadingfrom the discharge-ports to the driveway and provided withscreen-bottoms, means for raising said chutes from their deliveringpositions, a shaft extending from the groundfloor of the storehouseabove the roof thereof and disposed at a corner of the structure, ahopper supported in the upper portion of the shaft and having adischarge-opening prol story structure and provided in the second.

story with bins having ports and means for controlling the dischargetherethrough, a shaft extending from the bottom of the structure to thetop thereof and disposed at one corner, a chute leading into the bottomof the shaft, an elevator supported in the shaft and conveying the coalfrom the latter chute to the top of the shaft, a hopper supported in theupper portion of the shaft and provided the upper story of the structureand a gate for said opening, a screening-chute receiving the coal fromthe elevator and conducting the with an opening for discharging the coalinto
